Later in the battle, he is Digi-Xrossed with MetalGreymon to form a Cyber-Launcher for MetalGreymon to use against the Tankmon from the Bagra Army. However, once SkullSatamon and SkullGreymon (the other of DarkKnightmon's primary deputies) is absorbed by DarkKnightmon himself forming SuperDarkKnightmon, MetalGreymon (with Cyberdramon still in the form of the Launcher), Deckerdramon and Shoutmon X5 attempt to repel the blast that the Enhanced Black Knight fires at them and fortunately succeed in pushing it away far enough so that it does minimal damage to only the surface of the Zone (at most destroying the top of a rubbish heap, the blast however, completely destroying DarkKnightmon's tower).

Ferb next utilities him in the Disk Zone against Diamondmon and his forces. While at first he was able to defeat the Mammothmons and Tankmons from the Bagra Army with ease, he found the Bulbmon that Diamondmon had left in his stead, since he was tired from exhausting considerable energy, a challenge.
